Description
Technical field
The utility model relates to a kind of improved transformer injection system.
Background technology
Transformer is one of visual plant of transmission of electric energy, and the quality that transformer field is installed is directly connected to safe and reliable transmitting electric power.A transformer processed because of humidified insulation often spends long time to process again.At the needs of process installed, transformer definitely ensures that inner insulation is not made moist, the gap of transformer oil and transformer part does not exist any gas.
Transformer oil Main Function has three aspects: 1, as inside transformer insulation 2, transmit the heat that sends of heating position when transformer runs and carry out heat radiation 3, prevent the moisture of inside transformer solid insulating material around in medium from immersing time make moist fast.Gas is there is not for ensureing that in transformer installation process, insulating part does not make moist, in each spatia.Therefore on mounting process, following measure is taked; After mounting, before oiling, transformer needs to carry out vacuum treatment transformer.Its objective is and get rid of the moisture that in air residual in fuel tank and insulant and installation process, insulant absorbs.220kV level and above transformer must carry out vacuum oil, and 110KV person should use vacuum oil, and vacuum oil ensures that the oil-gap injected does not exist bubble, and there is bubble and can discharge in time, to meet the requirement of product insulation property.
The key step of usual vacuum oil is as follows: 1, high-power transformer hangs after inspection completes in working site, carries out back cover and vacuumize under the state without oil.Require all sealings place all good seals, each pipeline, valve, vacuum pump are all normal; 2, open the valve of vacuum line, start vacuum pump, transformer-cabinet is vacuumized, detects the deformation of casing simultaneously.The requirement of vacuum degree and time will meet relevant code; 3, after vacuum treatment reaches requirement and keep the regular hour, vacuum oil be carried out.Transformer oil slowly injects from tank bottoms.While vacuumize marginal not to enter transformer oil, oily fast general control, within 6t/h, control vacuum degree well; The oil injected can not with bubble.4, when transformer oil is added to from 200-300mm place, transformer oil box top, oiling is stopped; 5, maintain vacuum 2 hours or longer time, vacuum oil terminates.
But this existing vacuum oil technology has following problem in actual use:
From above-mentioned we can see, transformer, in the process of vacuum oil, in whole closed fuel tank, cannot judge to inject the height of oil level.Whether submergence iron core and winding, whether pasta has arrived case top is taken away by vacuum system, and when oiling is too much, excessive oil will be drawn into vacuum system by vacuum pipe, cause vacuum pump to damage, and excessive oil is discharged by vacuum pump, make large gauging excessive.So working site judges that the height of oil level brings certain difficulty.
Vacuum oil-injecting machine distance transformer generally has certain distance, and the connection of its pipeline is often very long, each connector poor quality of oiling pipeline, and in vacuum oil process, interface bubble can enter into body with oily stream, spreads in the oil clearance of each winding.Can not discharge in time.
The existence of bubble, extends the transformer quiet time put, can the office's of having influence on test of putting.Be 24 hours for the 110KV transformer quiet time put, the 220KV grade transformer quiet time of putting is 48 hours.Once had and put time short and power transmission of being eager because of quiet, caused the phenomenon that main transformer shell discharges over the ground.
Utility model content
The technical problems to be solved in the utility model is: for overcoming the problems referred to above, a kind of simplicity of design is provided but oil level can be reflected really, before oil enters transformer the improved transformer injection system that the gas in oil is processed again.
The utility model solves the technical scheme that its technical problem adopts:
A kind of improved transformer injection system, comprise the vacuum pump be connected with the vertically disposed tube connector in transformer upper end by vacuum line, described vacuum line is provided with the first control valve, described tube connector is also connected with collector box by oil level vacuum detecting pipeline, described collector box is communicated with the downside of described transformer by the second control valve, described oil level vacuum detecting pipeline upper end is provided with the 3rd control valve, described oil level vacuum detecting pipeline comprises vertically disposed observation pipeline, described observation pipeline adopts transparent material, described observation pipeline is carved with warning line, described warning line is positioned on the downside of described transformer top, and in vertical direction apart from described transformer top 200mm, described collector box is also connected with fuel charger by filling conduit, described filling conduit is provided with the 4th control valve, described fuel charger is communicated with oil tank.
Preferably, described tube connector length is 40-50cm.
Preferably, described oil level vacuum detecting pipeline is also carved with scale.
Preferably, fuel outlet valve is provided with on the downside of described collector box.
The beneficial effects of the utility model are: the utility model structure is simple, field fabrication is simple, convenient operation, solve in prior art and cannot observe oil level easily when vacuum oil, this novel principle utilizing linker, by simply designing real-time monitored level height in observation pipeline, basis is novel also arranges collector box at main transformer oil-in, the gas of being come in by oiling loop band, not entering before in main transformer case, is taken away by vacuum pump, is improved vacuum treated effect further.
